Hi,

I found another couple of instances of unsafe alloca usage in gdb, both
to do with trying to allocate memory on stack for a baseclass type. The
fix is on the lines of what was done in the following changeset:

http://sourceware.org/ml/gdb-cvs/2012-07/msg00044.html

I have verified that the fix does not cause any regressions on x86_64.
OK to commit?

Regards,
Siddhesh
